Abstract (en)

A method of making solid oxide solid oxide electrolyte membrane comprises steps (S1)-(S5). Step (S1), mixing a high molecular polymer and a first solvent to form a first mixed slurry; and homogenizing the first mixed slurry, to obtain a reagent A. Step (S2), mixing an oxide powder, a dispersant and a second solvent to form a second mixed slurry, treating the second mixed slurry, to obtain a reagent B. Step (S3), adding a protective agent into the reagent B to form a third mixed slurry, and homogenizing the third mixed slurry to obtain a reagent C. Step (S4), mixing the reagent A and the reagent C to form a fourth mixed slurry, and treating the fourth mixed slurry a fifth mixed slurry; and homogenizating the fifth mixed slurry to form a solid electrolyte slurry. And step (S5), producing the solid oxide solid oxide electrolyte membrane by a coating process.
